Quasiparticle Poisoning of Superconducting Qubits from Resonant Absorption of Pair-breaking Photons
Chuan-Hong Liu, David C. Harrison, Shravan Patel +8
The ideal superconductor provides a pristine environment for the delicate states of a quantum computer: because there is an energy gap to excitations, there are no spurious modes w…
Spurious Antenna Modes of the Transmon Qubit
O. Rafferty, S. Patel, C. H. Liu +4
Superconducting qubits are resonant absorbers of pair-breaking radiation. The metal pads that form the qubit capacitance support standing wave modes at frequencies of order 100~GHz…
Correlated Charge Noise and Relaxation Errors in Superconducting Qubits
C. D. Wilen, S. Abdullah, N. A. Kurinsky +11
The central challenge in building a quantum computer is error correction. Unlike classical bits, which are susceptible to only one type of error, quantum bits ("qubits") are suscep…
High-Fidelity Measurement of a Superconducting Qubit using an On-Chip Microwave Photon Counter
A. Opremcak, C. H. Liu, C. Wilen +10
We describe an approach to the high-fidelity measurement of a superconducting qubit using an on-chip microwave photon counter. The protocol relies on the transient response of a di…
Anomalous Charge Noise in Superconducting Qubits
B. G. Christensen, C. D. Wilen, A. Opremcak +9
We have used Ramsey tomography to characterize charge noise in a weakly charge-sensitive superconducting qubit. We find a charge noise that scales with frequency as over 5…
Digital coherent control of a superconducting qubit
Edward Leonard, Matthew A. Beck, JJ Nelson +15
High-fidelity gate operations are essential to the realization of a fault-tolerant quantum computer. In addition, the physical resources required to implement gates must scale effi…
